Abstract: A wind turbine blade is described having a lightning protection system, wherein the lightning protection system is arranged to protect conductive elements or modules used in or on the blade. In one aspect, the lightning protection system comprises a conductive band to be arranged around the circumference of the blade at the location of an internal conductive module, to prevent a lightning strike from penetrating the blade and potentially damaging the internal module. In another aspect, the lightning protection system comprises a lightning down-conductor having a signal-carrying structure, e.g. a signal cable, power cable, or a waveguide, integrated into the down-conductor. In a further aspect, the lightning protection system comprises at least one lightning receptor arranged to protect externally-mounted antennas from lightning strikes.

Abstract: A wind turbine blade comprising a system for monitoring the deflection of a wind turbine blade is described. The system comprises a wireless range-measurement system, having at least one wireless communication device located towards the root end of the blade and at least one wireless communication device located towards the tip end of the blade and internally within the blade body. Radio absorbing material is arranged internally in the blade body in the wireless communication path between the root-and tip devices.
